To wll whom it may concern.-

Be it known that l, LEENDERT Lsmnsnrus DAvm-ZuronREoEK, a subject of the Queen of the Netherlands, residing at 464: Heerenaeht, Amsterdam, in-the lfingdom of the etherlands, have invented a certain new and useful Improved i rooess for the Mannfacture of Coke Briquets, of which the following is a specification.

This invention relates to an improved process for the manufacture of brique'ts from coke and small coke, and has for its object to convert this kind of fuel into a more suitable It has not been ossihle hitherto to-iconiloine small coke Wit an agglomerant or bind ing medium in such a manner as to impart to the small coke a satisfactory form for ing purposes. For'this reason email colre has constituted hitherto in gas-works and the like a. by-product of little value, which, furthermore, becomes in time a source of 'great in- .convenience in such places.

The improved process of this invention has now for object to convert such small ooke into a valuable fuel 1) pressing it according he form of briquets or blocks which shall have the some fuel value as ordinary large-sized coke.

The improved rocess is as follows: The coke and the smal coke are reduced by grind- .there are added lime and cement, preferably Portland cement, in the proportions ofthree to ten parts of lime and one to three parts of Portland cement to one hundred parts of or sifting to a powder of the desired cer-' tam degree of fineness. To this cokepowder coke-powder, the materials being intimately mixed together. Then ten to twenty parts of water (preferably in the form of steam or spray) is added to the mixture, and the Whole is stirred thoroughly together. The Water causes the cement and the lime to set, wh re by the coke-powder is bound together. Tl mass is then formed by pressing in molds into hard briouets or blocks. The blocks produced in manner are then dried and are then ready for use. The addition of the lime has furthermore for its object to prevent atoo rapid combustion of the Toriquets. The amounts oi the cement and lime, as also the pressure which is to he einployed in pressing the blocks, depend on the purpose of use and on the re uirements which are demanded of the coke h oolzs as a fuel.

The product resulting from this process consists in a fuel mass com rising a mixture of coke in a comminuted 'oriin with slaked linreand cement, preferably Portland cement,
